Creation and development

Concept and introduction

Captain Rex, designated CT-7567 (often simply referred to as Rex), is a prominent clone trooper character in the Star Wars franchise, serving as the captain of the 501st Legion during the Clone Wars era. He was first introduced in the 2008 animated film Star Wars: The Clone Wars, directed by Dave Filoni and executive produced by George Lucas, where he emerges as a key ally to Jedi General Anakin Skywalker. In his debut, Rex leads his unit in the intense Battle of Christophsis, coordinating with Skywalker and Jedi Master Obi-Wan Kenobi amid a Separatist siege on the crystalline planet, demonstrating his tactical acumen and resolve from the outset. The character's creation stemmed directly from George Lucas's vision to humanize the , transforming them from anonymous soldiers into relatable individuals with distinct personalities and names. Lucas specifically directed the development team to craft a prominent who could represent this individuality, moving away from their portrayal as a in the films. This approach aimed to add emotional depth to the narrative, allowing audiences to connect with the clones' experiences in the war. Initially, the role drew inspiration from the Legends character Alpha-17, an elite ARC trooper from earlier Star Wars comics, but Lucas opted to create an original figure to avoid excessive alliteration with existing characters like Anakin, Ahsoka, and R2-D2. Under Dave Filoni's supervision and with input from the Lucasfilm animation team, Rex was refined in early development as a steadfast subordinate to Skywalker—embodying unwavering loyalty and battlefield expertise—while also positioning him as a guiding, almost fraternal mentor to the young Padawan Ahsoka Tano. This foundational characterization established Rex as an essential bridge between the Jedi leads and the clone army, influencing his portrayal throughout the animated series.

Design influences and changes

Rex's armor evolved across productions to reflect narrative progression and production shifts. In the 2008 animated film Star Wars: The Clone Wars, his Phase I armor featured prominent blue stripes on a white plastoid shell, establishing his leadership role within the 501st. As the series progressed into its third season, the design transitioned to Phase II armor, with Rex incorporating hybrid elements like the and from his Phase I helmet welded onto the new model, a modification explained by supervising director as Rex's preference for the original design's reliability over the updated version's features. This customization highlighted Rex's individuality amid the clones' uniformity, with the blue markings retained as a legion identifier. Further changes in later series emphasized aging and battle wear. In Star Wars Rebels, set years after the Clone Wars, Rex's armor appears weathered and scarred, with added tally marks on the helmet representing combat kills, symbolizing his veteran status and survival through the Empire's rise. The pauldron on his right shoulder, a standard indicator of captain rank among clones, was retained but shown as more battle-damaged to convey years of guerrilla activity. Helmet customizations, such as the Mandalorian-inspired "Jaig eyes" on the cheeks—denoting exceptional bravery—remained, underscoring Rex's personal modifications for distinction and honor. In the 2023 live-action series , Rex's design shifted to a more realistic rendering through for flashback sequences set during the , featuring Phase II armor with detailed texturing to match the photorealistic style of Disney+ productions. This adaptation maintained the blue stripes and hybrid helmet but adjusted proportions and lighting for seamless integration with live-action elements, marking a departure from the series' to a hybrid realistic approach. The weathered aesthetic from was not featured in these flashbacks, focusing instead on his prime-era appearance to reflect the timeline.

This approach draws on Baker's extensive experience voicing ensemble characters, allowing him to portray over 50 clones with subtle nuances based on their rank, personality, and role in the narrative. In the recording process, Baker typically works in isolation during sessions that can last four to six hours, imagining interactions with other characters while receiving direction remotely via video calls. To achieve authenticity, he incorporates military jargon and conducts into military procedures, layering emotional depth onto lines to convey the clones' shared yet unique experiences. For scenes involving large groups of clones, such as battle sequences, multiple recordings of Baker's performances are often layered in to simulate a full , enhancing the immersive quality of the dynamics without requiring additional actors. Baker's portrayal of Rex evolves across the series to reflect the character's aging and hardships. In Star Wars: The Clone Wars, Rex's voice starts with a higher pitch suited to a younger, more energetic soldier, gradually shifting to a gruffer tone as the war progresses.

A profound internal crisis arose for Rex when ARC trooper Fives uncovered a conspiracy involving behavioral inhibitor chips implanted in all clones, designed to ensure obedience. Assisting Fives in his investigation, Rex grappled with the revelation that these chips could compel clones to turn against the Jedi, forcing him to weigh loyalty to his brothers against the Republic's ideals amid Fives' desperate attempts to alert the Jedi Council. In the war's final days, Rex commanded a detachment of the 501st alongside former Jedi Padawan Ahsoka Tano in the Siege of Mandalore, launching a bold assault to capture Sith Lord Darth Maul and reclaim the planet from his Shadow Collective forces.

There, she reprogrammed the 2-1B medical droid to surgically remove the inhibitor chip from Rex's brain, freeing him from its control and allowing him to resist the order. Freed, Rex joined Ahsoka in a desperate defense against their former clone brothers, employing non-lethal tactics such as stunning them to avoid unnecessary deaths while escaping the Tribunal. With having commandeered the ship's only functional shuttle, and commandeered an antiquated Y-wing starfighter from the hangar. Pursued by vengeful clones led by ARC trooper , they initiated a risky maneuver to overload the Y-wing's engines, causing the vessel to crash onto a nearby unnamed moon. The impact destroyed the fighter and killed the pursuing clones aboard their transport, enabling and to stage their deaths convincingly. Emerging from the wreckage unscathed, they interred their armor—'s marked with blue 501st insignia—and Ahsoka's lightsabers in a shallow grave on the moon's surface, symbolizing the end of their public identities. In the immediate aftermath, Rex parted ways with , who continued her own path in secrecy, while Rex buried his past as a officer, assuming the role of an unassuming to avoid the Empire's of surviving clones and sympathizers.
